The clearing action does not need to be performed at the electronic device 200, which is convenient for the user , Restore the real writing experience, and perfect the writing system 1000 for writing.
在本实施方式中,导电橡皮21包括橡胶体和填充在橡胶体内的导电粒子。In this embodiment, the conductive rubber 21 includes a rubber body and conductive particles filled in the rubber body.
如此,可以使得橡胶体具备的导电功能以使得触控传感器模块12能够感测到导电橡皮21在书写区11的接触面积和移动轨迹。In this way, the conductive function possessed by the rubber body can be made so that the touch sensor module 12 can sense the contact area and the moving track of the conductive rubber 21 in the writing area 11.
在某些实施方式中,触控传感器模块12包括电容式触控传感器121,电容式触控传感器121用于与导电橡皮21之间形成耦合电容,并根据耦合电容的变化感测接触面积和移动轨迹。In some embodiments, the touch sensor module 12 includes a capacitive touch sensor 121. The capacitive touch sensor 121 is used to form a coupling capacitance with the conductive rubber 21 and sense the contact area and movement according to the change in the coupling capacitance Track.
具体地,由于导电橡皮21具有导电功能,因此,在用户使用导电橡皮21对书写区11的字迹进行擦除时,导电橡皮21能够和电容式触控传感器121形成耦合电容,在导电橡皮21进行移动擦除时,两者之间的耦合电容会发生变化,电容式触控传感器121可以根据耦合电容的变化来感测导电橡皮21与触控装置10的接触面积和移动轨迹。Specifically, since the conductive rubber 21 has a conductive function, when the user uses the conductive rubber 21 to erase the writing of the writing area 11, the conductive rubber 21 can form a coupling capacitance with the capacitive touch sensor 121, During mobile erasing, the coupling capacitance between the two will change, and the capacitive touch sensor 121 can sense the contact area and movement track of the conductive rubber 21 and the touch device 10 according to the change in the coupling capacitance.
请再次参阅图1,在某些实施方式中,导电橡皮21包括头部211,头部211具有能 够与书写区11接触的至少两个接触区212。具体地,在用户使用导电橡皮21清除书写区11的字迹时,一般采用头部211的接触区212与书写区11进行接触以达到清除字迹的目的。通常地,在本实施方式中,多个接触区212的面积不同。如此,用户可以根据需要进行字迹擦除的区域大小来选择采用不同的接触区212对书写区11的字迹进行擦除。可以理解,在其他的一些实施方式中,多个接触区212的面积也可以全部相同或者部分相同。Please refer to FIG. 1 again. In some embodiments, the conductive rubber 21 includes a head 211 having at least two contact areas 212 that can contact the writing area 11. Specifically, when the user uses the conductive rubber 21 to erase the writing of the writing area 11, the contact area 212 of the head 211 is generally used to contact the writing area 11 to achieve the purpose of erasing the writing. Generally, in this embodiment, the areas of the plurality of contact regions 212 are different. In this way, the user can choose to use different contact areas 212 to erase the writing of the writing area 11 according to the size of the area where the writing needs to be erased. It can be understood that, in some other embodiments, the areas of the multiple contact regions 212 may be all the same or partly the same.
在采用不同的接触区212进行擦除时,触控装置10能够感测导电橡皮21与书写区11的接触面积的大小,从而根据接触面积的大小和移动轨迹形成清除指令。When different contact areas 212 are used for erasing, the touch device 10 can sense the size of the contact area between the conductive rubber 21 and the writing area 11, thereby forming a clear instruction according to the size of the contact area and the movement trajectory.
此外,在某些实施方式中,触控装置10的触控传感器模块12还用于识别接触面积是否满足预设条件,并在接触面积满足预设条件时,根据操作信息生成清除指令。In addition, in some embodiments, the touch sensor module 12 of the touch device 10 is also used to identify whether the contact area meets the preset condition, and when the contact area meets the preset condition, generate a clear instruction according to the operation information.
具体地,在使用导电橡皮21对书写区11的字迹进行擦除时,与书写区11接触的是导电橡皮21的头部211的接触区212。在使用导电橡皮21的接触区212对书写区11的字迹进行擦除时,导电橡皮21与书写区11的接触面积基本保持不变,因此,可以通过判断接触面积是否满足预设条件来确定与书写区11接触的是否为导电橡皮21。Specifically, when the writing of the writing area 11 is erased using the conductive rubber 21, the contact area 212 of the head 211 of the conductive rubber 21 is in contact with the writing area 11. When the contact area 212 of the conductive rubber 21 is used to erase the writing of the writing area 11, the contact area of the conductive rubber 21 and the writing area 11 remains basically unchanged. Therefore, it can be determined by judging whether the contact area satisfies the preset condition. Whether the writing area 11 is in contact with the conductive rubber 21 or not.
在上述实施方式中,预设条件是指根据导电橡皮21的多个接触区212的面积进行预设的数值范围。也就是说,在本实施方式中,只有接触面积满足预设条件,即接触面积在预设的数值范围内时,触控传感器模块12才会根据接触面积和移动轨迹生成清除指令,若接触面积不满足预设条件,即接触面积不在预设的数值范围内,即使存在接触和移动轨迹,也不会生成清除指令。例如,假设导电橡皮21具有五个面积不同的接触区212,各个接触区212的面积分别为0.2cm 2、0.5cm 2、1cm 2、1.5cm 2、和2cm 2,由此,预设的数值范围可以设置成0.2-2cm 2,也即是说,只有在导电橡皮21与书写区11的接触面积位于0.2-2cm 2的范围内时,才会根据操作信息生成清除指令。若接触面积不在预设范围内,则表示此时与书写区11接触的不是导电橡皮21,不会生成清除指令。 In the above embodiment, the preset condition refers to a preset value range according to the areas of the multiple contact regions 212 of the conductive rubber 21. That is to say, in this embodiment, only when the contact area meets the preset condition, that is, the contact area is within the preset value range, the touch sensor module 12 will generate a clear command according to the contact area and the movement trajectory. The preset condition is not satisfied, that is, the contact area is not within the preset value range, and even if there is contact and movement trajectory, no clear command will be generated. For example, it is assumed that the conductive rubber 21 has five contact areas 212 with different areas, and the area of each contact area 212 is 0.2 cm 2 , 0.5 cm 2 , 1 cm 2 , 1.5 cm 2 , and 2 cm 2 respectively . Therefore, the preset values The range can be set to 0.2-2 cm 2 , that is to say, only when the contact area of the conductive rubber 21 and the writing area 11 is within the range of 0.2-2 cm 2 , the clear instruction will be generated according to the operation information. If the contact area is not within the preset range, it means that the conductive rubber 21 is not in contact with the writing area 11 at this time, and no clear instruction will be generated.
如此,可以防止由于用户的误触而导致清除掉了电子装置200所显示的笔迹,提高了用户体验。In this way, it is possible to prevent the handwriting displayed by the electronic device 200 from being erased due to the user's wrong touch, thereby improving the user experience.
在其他实施方式中,上述的预设条件也可以是直接根据多个接触区212的面积而设定的多个固定数值。也就是说,只有接触面积为预设的多个固定值中的任一个时,触控传感器模块12才会根据接触面积和移动轨迹生成清除指令,若接触面积与预设的多个固定值中的任一个都不匹配,即使存在接触和移动轨迹,也不会生成清除指令。例如,假设导电橡皮21具有五个面积不同的接触区212,各个接触区212的面积分别为1cm 2、1.5cm 2、2cm 2、2.5cm 2和3cm 2,由此,预设的多个固定数值可以是1cm 2、1.5cm 2、2cm 2、2.5cm 2和3cm 2,也即是说,只有在导电橡皮21与书写区11的接触面积与上述的固定数 值相匹配时,才会根据操作信息生成清除指令。若不匹配,则表示此时与书写区11接触的不是导电橡皮21,不会生成清除指令。此外,还可以理解的是,在上述实施方式中,可以通过设计导电橡皮21的造型等方式来设置接触区212的面积,并且保证导电橡皮21在使用过程中,各个接触区212的面积保持不变。 In other embodiments, the aforementioned preset condition may also be a plurality of fixed values directly set according to the areas of the plurality of contact regions 212. That is to say, only when the contact area is any one of the preset multiple fixed values, the touch sensor module 12 will generate a clear command according to the contact area and the movement trajectory, if the contact area is within the preset multiple fixed values None of them match, even if there is contact and movement trajectory, no clear command will be generated. For example, it is assumed that the conductive rubber 21 has five contact areas 212 with different areas, and the area of each contact area 212 is 1 cm 2 , 1.5 cm 2 , 2 cm 2 , 2.5 cm 2, and 3 cm 2 , respectively. The value can be 1cm 2 , 1.5cm 2 , 2cm 2 , 2.5cm 2 and 3cm 2 , that is to say, only when the contact area of the conductive rubber 21 and the writing area 11 matches the above-mentioned fixed value, it will be based on the operation The message generates a clear instruction. If there is no match, it means that the conductive rubber 21 is not in contact with the writing area 11 at this time, and no clear instruction will be generated. In addition, it can also be understood that in the above embodiments, the area of the contact area 212 can be set by designing the shape of the conductive rubber 21 and the like, and the area of each contact area 212 is maintained during the use of the conductive rubber 21 change.

In addition, the housing 24 may be sleeved on the conductive rubber 21, the rubber at least partially protrudes from the housing 24, so that when the conductive rubber 21 needs to be replaced, there is no need to replace the housing 24, but only need to remove the conductive rubber 21 from the housing Take out the body 24 and replace the conductive rubber 21. In this way, even if it is convenient for the user to replace the conductive rubber 21, the use cost of the handwriting removal tool 20 is also reduced.
需要说明的是,在本实施方式中,壳体24由导电材料制成例如导电金属。在使用过程中,壳体24以及导电橡皮21将人体的电流传输到触控传感器模块12的电容式触控传感器121上,从而使得笔迹清除工具20与电容式触控传感器121之间形成耦合电容。In addition, in this embodiment, the case 24 is made of a conductive material, for example, a conductive metal.
